Usually nice weather , i dont know the answer to the second part
Answer:
C) specific heat capacity
Explanation:
As we know that heat given to the system to change the temperature is given as
here we know that
Q = thermal energy given to the system
s = specific heat capacity of the system
= change in temperature
so here we know that
here we know that heat given to the two cubes is of same amount as well as the mass is same but the final temperature is different because of the specific heat capacity (s)
So correct answer would be
C) specific heat capacity
Answer:
The change in angular momentum is
Explanation:
From the question we are told that
The initial angular velocity of the spinning top is
The angular velocity after it slow down is
The time for it to slow down is
The rotational inertia due to friction is
Generally the change in the angular momentum is mathematically represented as
substituting values
